Asc Engineered Solutions 308301605 Flanged Union 3 in

Product Description

The ASC ENGINEERED SOLUTIONS 308301605 is a 3-inch Class 125 black cast iron flanged union designed for joining and disconnecting piping sections in commercial and industrial plumbing and mechanical systems. Flanged unions allow for fast removal of inline components without cutting pipe, making them a practical choice for systems requiring periodic service or equipment changeouts. The Class 125 pressure rating and black cast iron construction make this fitting suitable for low-pressure water, steam, and general service piping applications. This part is installed by licensed plumbers and pipefitters working on commercial mechanical systems.

This flanged union is used in 3-inch piping systems where a removable, bolted connection is required. Typical applications include boiler rooms, mechanical rooms, and industrial process piping where cast iron flanged fittings are specified. The flanged design conforms to Class 125 dimensional standards, making it compatible with other Class 125 flanged components in the same pipeline. Domestic manufacture supports project specifications that require USA-made materials.

Key Features

• Class 125 pressure rating suitable for low-pressure water and steam service
• Black cast iron construction for durability in commercial and industrial environments
• Flanged connection allows bolted, removable pipe joints without cutting pipe

Compatibility

Designed as an OEM-style replacement or new-installation flanged union for 3-inch Class 125 cast iron flanged piping systems in commercial plumbing and mechanical applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable plumbing codes such as the IPC. The system must be depressurized and drained before removing or installing flanged unions. A gasket appropriate for the service fluid and pressure class should be used at the flange face, and fasteners should be tightened in a cross pattern to ensure even seating. Follow local code requirements for flange bolt torque procedures and gasket material selection.
